@Eklipse - You're absolutely right, in the sense that change is not always good. That is not at all what I tried to say. I was merely arguing that while this claim by Jai
All empires have collapsed from change that was either radical and of quick order or by infinitesimal compromise with the opposition to the normal political order
might be true, it does not implicate that "empires" must always stick to their historical values or system to survive, in contrary to how Jai represented it. Instead, it means that the world is changing all the time whether we want it or not, and the empires that prevail are those who understand the need to adapt. The Kingdom of Denmark keeps going strong and happy, even when their jurisdiction and values are quite far from the Viking era.
As for the Soviet Union, it didn't just appear from nowhere and it certainly wasn't just a "introduction of radical changes". It was the direct result of the failures in the Tsarist system - failures to adapt to the growing social movement. Countries who acknowledged that the world was changing introduced democracy, constitution and social benefits, and they continue their existence today.
The collapse of USSR, in turn, didn't happen just because the basic idea was too radical - it happened because the system was too obsessed with it's own ideals to understand that the world in 1990 wasn't the same as it was in 1917.
To sum it up: if we look at history we see empires destroyed by radical change. We can make two contradictory analysis:
1) Change is what destroys empires, so we must avoid changing too much in order to survive (as Jai argumented), or
2) Change is inevitable, so we must try to do it in a controlled manner in order to survive.
In my opinion, the history arguments clearly on the latter.
